After creating a Fedora 37 virtual machine, you may encounter the issue of sound missing in the virtual machine. If so, it is likely due to one of Fedora's system packages not having been updated correctly and not containing sound device drivers.
To fix it, please follow these steps:
1. Inside the Fedora virtual machine, open Terminal and execute the following command:
sudo dnf --refresh upgrade
2. The command may take a while to complete. Once it is completed, restart the virtual machine.
